The original piston cracks or the lip seal hardens, causing loss of hydraulic hold-off and letting the one-way clutch freewheel — resulting in no engine braking, high RPM overrun on deceleration, and eventual sprag or coast clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full function instantly.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003ePerfect fit for 1995-2005 models including:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eChevrolet Malibu, Cavalier\u003c\/li\u003e\n \t\u003cli\u003ePontiac Grand Am, Sunfire\u003c\/li\u003e\n \t\u003cli\u003eOldsmobile Alero, Cutlass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSymptoms of a bad ONE-piston:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul dir=\"auto\"\u003e\n \t\u003cli\u003eEngine revs freely when coasting in gear\u003c\/li\u003e\n \t\u003cli\u003eNo engine braking (especially in lower gears)\u003c\/li\u003e\n \t\u003cli\u003eRatcheting noise from one-way clutch\u003c\/li\u003e\n \t\u003cli\u003eBurnt coast clutches or broken sprag on teardown\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003eDrop this ONE-piston in during your next rebuild and get that factory-correct engine braking back — no more runaway revs!\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e All parts are distributed, not designed or manufactured, by Stellar Automotive Group.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAdd this critical 4T40E ONE-piston to your cart today and feel the difference on every downshift!\u003c\/p\u003e","brand":"Trans Parts Direct","offers":[{"title":"Default Title","offer_id":52425242673333,"sku":"33820 UP","price":33.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/3872\/0181\/files\/33820-UP-scaled.jpg?v=1786618690","url":"https:\/\/transpartsdirect.com\/products\/stellar-automotive-group-4t40e-one-way-coast-clutch-piston-fits-gm-95-05","provider":"Trans Parts Direct","version":"1.0","type":"link"}
